The latter comprises three fundamental components made up by a special section of the spring (9), bushes (11) for embedding same in the bedstead frame (10) and supplementary caps (12) for finishing off the spring-to-bush assembly. The section making up the springs (9) adopts an inverted ''U'' shape cross section with short vertical arms with a broad horizontal stretch.</p> |
